Complex plasmas consist of highly charged micrometer-sized grains injected into a low temperature noble gas discharge. The particles interact with each other via a screened Coulomb potential, and can form gaseous, liquid or solid states. On ground, gravity compresses the system and prevents the generation of larger, three-dimensional particle clouds. The Ekoplasma project, a Russian-German cooperation, is the future laboratory for the investigation of complex plasmas under microgravity conditions on the International Space Station (ISS). The essential part of Ekoplasma is the newly developed Zyflex chamber – a large, cylindrical plasma chamber with parallel, rf-driven electrodes and a flexible inner geometry. It is designed to extend the accessible experimental parameter range and to allow an independent control of the plasma parameters, therefore increasing the experimental possibilities and expected knowledge gain significantly. The experimental setup and the current project status will be presented, as well as selected results of experiments on earth and in parabolic flights, which demonstrate the scientific possibilities of this new laboratory.
